Left border in a DataGrid column is invisible

I have created a DataGrid as below, but the left border of the Unit column is invisible.
I have checked the datagrid properties but does not seem to find any property that affect this,
Any help is appreciated. Thanks in advance!

Your renderer code looks a little strange. This works, and

Changing a datagrid column image according to the datagrid column value

Flash Builder 4.5 / SDK 4.5.1.
Fairly new to Flash Builder & Flex
Application targets tablets so it's a "mobile" project.
Been beating my head up against the wall on trying to figure out how to do this. Watched videos on Lynda.com. Read Adobe "docs" till my eyes glaze over. Takes me about 2 lines of code in my corresponding .NET project doing the same thing.....
Tried numerous examples. Inline rendering, external rendering files per the examples.
I have a response field in the database and corresponding column in the s:datagrid. If the "reportInfoResponse" field is null (not answered), show an image with a question mark. If yes show an image with "Yes" on it. Same for a no answer.
I get errors of:
1120:Access of undefined property negativeAnswer.
1120:Access of undefined property affirmativeAnswer
1120:Access of undefined property reportInfoResponse
1120:Access of undefined property showResponseImage
If I put this in an external rendering file I also get an error where it can't access the datafield (reportInfoResponse). I've tried data.reportInfoResponse, {data.reportInfoResponse}, {reportInfoResponse} and just plain reportInfoResponse the external rendering file with no luck. I've tried single and double quotes around Y and N. According to all the examples (not to say there aren't more!), I should be able to reference data.reportInfoResponse in the external file and things should be fine. Of course, the examples are bare bones code and I don't have a clue if any importing of classes or other items need to take place. I never see any references of such. The examples also show the image embedding and changing the image by using imageID.source=... In my code it tells me it can't find it.
I have put (ERROR HERE...) on the lines where I'm getting the error messages. I've eliminated a lot of database scripting and such cause that's all working.
Any and all suggestions would be appreciated as I'm pulling out what little hair I have left.......and that's not much at my age........ And yes, I probably could do it by just show text in the column, but that's not what the customer wants... There are other columns I need to do this for so I figure if I can get 1 done and working, the rest are a snap. I CAN use inline or external rendering to show an image. It's the changing it that is the catch.........
Thanks in advance!

Ioan Thanks for the reply.
Probably my previous explanation of the problem was a little incomplete. Let me give a better description.
The situation is something like this.
I have a requirement in which the customer wants the column header to reflect the 'keep filter value' restriction that he does dynamically in the query report.
i.e:
-- usually the kf column header shows 'sales volume'
-- column header with text variable of the Calender year / month variable -- 'sales volume for 2000 oct'
-- but when the report is run, if the user wants to go and change the filter: calender year / month > rt clk > keep filer value > select Jan 2003.
The kf column header still shows 'Sales Volume 2000 Oct'
How to make the column header change to 'sales volume for Jan 2003' ?
Any suggestions greatly appreciated.
Thanks,

How not to sort datagrid column on double click

Hello,
I am currently building an application containing a datagrid for data representation. I've created a custom datagridheader in order to add a input text for filtering the columns (see code below).
My goal is to hide the textinput, and then show it on a double click on the header. So i would like to know how to avoid the sort of this column each time i double click.?

Based on your idea, i've intercepted the click event and I use stopImmediatePropagation.
THen i added an image to sort the column. So if the image is clicked the sort is ok.

Adding a Tree into a datagrid column

I have a requirement where I have to create a datagrid with
one of the columns having a tree control. The problem I am trying
to resolve is how to dynamically change the height of the datagrid
column which has the tree when the tree is collapsed and
dynamically increase the datagrid column height when the tree is
expanded.
Is is feasible ? Am I chasing a wild dream ?
Any help will be greatly appreciated...
Thanks

Darin,
Thank you for responding. I was able to get a tree display in
a datagrid. I am going to attach all the code.
The problem I am facing is, I need two clicks to expand a
tree in the datagrid column so that both the tree to expand and the
datagrid column to adjust its height. Let me know why this is so.
May be, being a newbie, I am completely off the track here. Thanks
in advance.

Need help adding image to datagrid column

Hi,
Can anyone tell me how to add an image to a datagrid column?
I have created a flex library project which contains a mxml component with a datagrid, an item renderer mxml component which rendered the image within the datagrid column depending on the value coming back from the database for that column and a folder 'assets' which hold all the images. When I add the library to my main project and call the mxml component with the datagrid an image place holder is visible in the datagrid column but not the image. However, if I take the image out of the library project and added to an 'assets' folder in the main project the image is displayed in the datagrid column.
It looks like, even though the images are in the flex library project and only the flex library project is trying to display the images in the datagrid, the library project is looking in the main application project folder for the image.
Does anyone know why this is happening and how to fix it?
Thanks in advance for an help,
Xander.

I have tried embedding the images in my library but it still didn't work. Also I can't embed the image as I'm using the value of the column to complete the image name, for example in my mxml item renderer component I have the added the following code
<mx:Image source="@Embed(source='assets/' + data.mycolumnvalue + '.png')" tooltip="{data.mycolumnvalue}"/>
but nothing is displayed.

How do I show an image in a DataGrid column?

I'm not sure that this is possible. I would like to show an
image in a datagrid column based on the data that the grid is bound
to. Is there any way to do this? I'm using Beta 3.
Thanks!

Yes, you need a custom itemRenderer. This can be inline or a
custom class.

Would really need to see the code to see the extent of the damage Photoshop html has caused. This is a typical problem when exporting html from Photoshop OR trying to assemble the slices into one gigantic table where the cells have been split and merged numerous times which causes distortion.
The idea, looking at your page, would be to insert a simple 3 column x 1 row table into Dreamweaver then insert the components that make up your page into their realtive columns. Using this simple construction method will ensure that all the page elements remain seperate and cannot interact with other element in different cells, which is what is NOT happening in your construction at the moment.

Flex 3: DataGrid Column width on resize

Hello experts,
I am facing an issue with width of DataGrid columns. We are using Flex 3.2.
I am setting the widths for columns in creationComplete handler of DataGrid. When the browser window is resized, say restore down and then maximize,
the column widths are changing. Please find the code below:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" height="100%" width="100%">
<mx:Script>
 <![CDATA[
 import mx.core.ScrollPolicy;
 [Bindable]
 private var isVisible:Boolean = true;
 private function creationCompleteHandler():void{
 dataGrid.horizontalScrollPolicy = ScrollPolicy.ON;
 artist.width = dataGrid.width * 0.40;
 album.width = dataGrid.width * 0.50;
 Price.width = dataGrid.width * 0.10;
 dataGrid.horizontalScrollPolicy = ScrollPolicy.OFF;
 ]]>
</mx:Script>
<mx:DataGrid id="dataGrid" width="80%" height="100%" creationComplete="creationCompleteHandler()">
 <mx:ArrayCollection>
 <mx:Object Artist="Pavement" Price="11.99"
 Album="Slanted and Enchanted" />
 <mx:Object Artist="Pavement"
 Album="Brighten the Corners" Price="11.99" />
 </mx:ArrayCollection>
 <mx:columns>
 <mx:DataGridColumn id="artist" dataField="Artist"/>
 <mx:DataGridColumn id="album" dataField="Album" visible="{isVisible}"/>
 <mx:DataGridColumn id="Price" dataField="Price" />
 </mx:columns>
 </mx:DataGrid>
</mx:Application>
Is there anything wrong i am doing here? Please help me in resolving this.
Thanks,
Srilatha

Hi Srilatha,
DataGrid width is 100% and the main application width also 100%, So the
DataGrid will try to occupy the whole window, when you do "restore down" &
"maximize" Application width will change.. and it will effect DataGrid and
its columns also. Try to give some fixed width for dataGrid and you can
expect the result.
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"
height="100%" width="100%">
 <mx:Script>
 <![CDATA[
 import mx.core.ScrollPolicy;
 private var isVisible:Boolean = true;
 private function creationCompleteHandler():void
 dataGrid.horizontalScrollPolicy = ScrollPolicy.ON;
 artist.width = dataGrid.width * 0.40;
 album.width = dataGrid.width * 0.50;
 Price.width = dataGrid.width * 0.10;
 dataGrid.horizontalScrollPolicy = ScrollPolicy.OFF;
 ]]>
 </mx:Script>
 <mx:DataGrid id="dataGrid" width="500" height="100%"

Dynamic DataGrid columns

How can I get this example to wok with <mx:HTTPService>
insead of the inline <mx:XML> ?
Dynamic DataGrid columns
Example of how to dynamically create DataGridColumns
A completely dynamic DataGrid example.
This example uses the xml from the Flexstore example. It
examines the first product node and uses that to create the
definitions for the columns. There is some example logic to change
the columns properties.
It then instantiates the GataGrid and its columns array,
assigns the properties, and then the dataProvider, and then adds
the dataGrid to the application container.
The example is fully self-contained, since a portion of the
catalog.xml file is included in the mxml.

Editable Datagrid Column

I have to make a datagrid column editable during runtime based on the data. If the column has a specific data then the column should not be editable otherwise it should be editable. Can we do it in flex ? please show some pointers.

I don't have any examples , but you should probably have a custom itemrenderer for your datagrid which contains a textarea. In the itemrenderer should override set data( value:Object ):void. In that function you check a condition to see if the textarea "editable" value should be set to true or false. Below I have some pseudo-code.
<s:Itemrenderer>
override public function set data( value:Object ):void
if( object.decidingValue > 0 )
TnA.editable = false;
else
TnA.editable = true;
<s:TextArea id="TnA" />
</s:Itemrenderer>
or you could just put the code in the TextArea declaration
<s:TextArea id="TnA" editable="{data.decidingValue > 0}" />
(TextInput area is probably more appropriate than a textarea , but the logic is the same )
If this response was helpful please mark it as such.

ItemRenderer in a datagrid column setStyle() does not do anything to the appearance

I have a custom ItemRenderer in a datagrid column, however
the setStyle() does not do anything to the appearance. when it is
called. Any ideas?
<mx:DataGridColumn dataField="area" width="50"
headerText="Area">
<mx:itemRenderer>
<mx:Component>
<mx:Text>
<mx:Script>
<![CDATA[
override public function set data( value:Object ) : void {
super.data = value;
setStyle("Color",0xff0000);
if(data.area == 'G'){
setStyle("backgroundColor",0xff0000);
}else{
setStyle("backgroundColor",0xff0000);
]]>
</mx:Script>
</mx:Text>
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>

Your renderer code looks a little strange. This works, and
may get you started:

Datagrid column text styles

I have a datagrid column that contains strings in this
syntax: ##% (##%)
When the percentages are over 0% I'd like the text to be
green; when the percentages are under 0%, I'd like to change the
text to red. Apart from breaking this into two columns, how can I
change the colors of different strings inside the same datagrid
column?
Thanks,
Tom

Tom,
One way to do this would be to make a custom ItemRenderer
based on a Label for your dataGrid column. Then, just test whether
you have positive or negative values for your dataField. If it is
negative, use a setStyle('color', 0xFF0000) for red. Here is a
basic example:
<?xml version="1.0" encoding="utf-8"?>
<mx:Label xmlns:mx="
http://www.adobe.com/2006/mxml">
<mx:Script>
<![CDATA[
override public function set data(value:Object):void {
super.data = value;
if (value != null)
if(value.fieldValue >= 0) //fieldValue will need to match
your dataField value from your dataProvider of your dataGrid. You
might need to convert it to an int to compare.
setStyle("color", 0x00DD00);
} else {
setStyle("color", 0xDD0000);
super.invalidateDisplayList();
]]>
</mx:Script>
</mx:Label>
Then in your main app:
<mx:DataGridColumn headerText="Drill Type"
dataField="fieldVAlue" width="105"
itemRenderer="renderers.RedGreen"/>
This assumes that your mxml component is named
'RedGreen.mxml' and is in the 'renderers' directory. You can adjust
this to fit your project as needed. I hope this helps.

Datagrid column in module causing memory leak

Hi All
I'm having trouble with a DataGrid column preventing a module from being release properly. I can't imagine this is the intended behaviour.
Using this simple test case, a WindowedApplication and an mx:Module I wonder if anyone else can reproduce this problem. The issue goes away if you simply comment out the GridColumn Instance.
Can anyone offer any advice?
Many thanks
James

OK, So I've done some more testing. Creating the GridColumn in AS during the creationComplete event is a slight improvement. It seems to allow the DataGrid and the Module be GC'd, but it's still leaking memory somewhere. I just can't get my head around the Profiler. Also, it's going to be a massive headache if we have to rewrite our application to create all the GridColumns in AS. Surely this shouldn't be necessary?

try wrapping your component inside the itemrenderer tag

Datagrid column header word wrap issue

Hi All,
I'm passing dynamic text to a datagrid column header. The word wrap is true but it's not working.
Any ideas how to fix this issue?
DataGridColumn headerText="{myVar.text} Total" headerWordWrap="true"
Thanks
Johnny

@Johnny,
Try to make use of the headerRenderer property and use <mx:Text /> control as a renderer so that your headerText gets wrapped..
Thanks,
Bhasker
